`COOKING* UTENSIL.

Application sled April 1s, 1924. serial No. 701,344.

To all whom t may concern.' v l Be it known that we, HERMAN G. Pimen- LER, a citizen of the United States, and resident of New York city, borough of Manhattan, county and State of New York, andv CHARLES J. MARKS, a citizen of the United States, and resident of Paterson, county of Passaic, State of New Jersey, have invented certain new and useful lniprovcments in Cooking Utensils, of which the following is a specification.

In United States Letters -latent N 0. 1,106,837, granted to us August 11, 1914, for cooking utensils, wherein a vessel is provided with a lid and a yoke having resilient means for retaining the lid upon the vessel, a valve is provided to release steam pressure from within the kettle. The pressure within the kettle waspcontrolled by the weight 2o of the valve and a spring pressing thereon, and there ywas no variation either in the pressure of the lid upon the kettle or of the weight of the valve against its seat.

Our present invention relates to improvements in the class of cooking utensils referred to and has for its object to provide means to control the pressure of the lid upon the kettle as wel] as to control the resistance of the valve to pressurel within the 3o kettle.

In accordance with our invention vfood may be cooked with relatively light or normal steam pressure within the kettle, or with increased steam pressure within the kettle which may be caused by increasing the resistance of the escape valve as wellas by increasing the pressure of the lid upon the kettle.

Our invention comprises vnovel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the acompanying drawings forming a part hereof, where- Fig. 1 is a partly sectional side elevation of a cooking utensil embodying our invention; f

Fig. 2 is an enlarged detail section of part of Fig. v, showing parts in a different position; and

Figs. 3 and 4 are cross sections, respectively on lines 3, 3, and 4, 4, in Fig. 2.

Similar numerals of reference indicate corresponding parts in the several views.

At 1 is indicated a kettle or pot which may be of any suitable construction, preferably of cast metal to retain the heat, and shown provided with an outer overhanging or hook-like flange or extension 2 adjacent to its upper edge. A t 3 is a lid or cover to tit on said edge. By preference the meeting edges of the kettle and lid are in the form of ground joints to form a tight closure without requiring packing. A suitable grate 4 may be provided to rest upon the bottom of the kettle. A yoke 5 is adapted to extend over the lid and is shown provided with hook-like ends 5, 5" to engage the ange 2 to retain the yoke in position over the lid. The yoke is shown provided with a movable finger piece 5c having the end 5l to engage flange 2 and pivotally connected with the yoke at 6. An extension 5d over the linger piece enables the ready operation of the finger piece by pressing upon the extension. The foregoing arts are substantially the same as set for in our aforesaid Letters Patent.

A spring 4pressed plunger 7 is 4slidably guided in a bore 8 in the yoke located in position to be substantially central with the yoke over the lid. Said plunger is normally i ressed toward the lid by spring 9 within )ore 8, the lower end of which spring is shown pressing aginst the plunger and the outer end of the spring bears against au adjustable member 10, shown in the form of a nut, having an extension 10a provided with projections at 11, in the form of a wing-nut, for convenience in rotating the member or nut. The threads on the member cooperate within internal threads 12 at the outer end of bore 8, and a stop 13, shown 'in the-form of a pin located transversely in the projecting portion 14 of the yoke, opposes the member 10 to limit its outward movement. When the member 10 islocated at the outer portion of bore 8, as against the stop-13, the pressure of spring 9 upon plunger 7, hence u on lid 3,' will be norvmal or relatively lig t, and when the member 10 is screwed into bore 8 the pressure of the spring upon the plunger and thus upon the 11d will be increased.

The lunger 7 is adapted to fit within a central y disposed recessed knob or finger piece 15 on lid 3 which has an outlet passage 16"leading therethrough andl through the lid to register with a port 17 that communicates rwith central bore 7aA in plunger -7, said plunger being provided with a latouter end beyond member 10 the rod is provided with a stop at 20, shown in the form of a nut, the lower end of the rod being adapted, under some conditions, to rest upon a ball valve 21 locatedat the bottom of bore 7a of `plunger -7 to 'normally or normal ,close the outlet from the kettle through port 17. e plunger is shown Kprovided with a stop 22, shown in; theA form of a nut, having a bore receiving rod 19 and secured by threadsl at the upper end of bore 71-of the plunger. The spring 9 rests upon the nut 22 and the lower or inner end of rod 19 is provided with a head or enlargement 19, between valve 21 and nut 22, so that the head 19a may move freely within bore 7a between nut 22 and the valve. The rod 19 will retain plunger 7 within bore 8.

The arrangement of the parts is such that when memberV 10 is raised, as in Fig. 1, it will engage the stop "or mit 20 on rod 19 and raise the latter away lfrom valve 21, in which position of the parts the plunger 7 is pressed against the lid by the light ressure of spring 9, and valve 21 will be ree `from the rod and will control the pressure of steam or vapor within the kettle according to the weight of said valve. The spring9 also by pushing uponplunger 7 retains the lid 3 upon the kettle with normal pressure. When it is desired to increase the steam pressure within the kettlev beyond kthe normal pressure, maintained by valve 21 `the member 10 is screwed linto the borevv 8 to increase the pressure of lspring 9 against the lidiy and the rod 19 Will be `correspondingly lowered, whereupon when member 10 is entered in bore 8 suf- ,ciently yfar the rod 19 will rest upon valve .21 and the weight of the r'od willbe superlmposed upon the valve when the member 10 moves away fromnut 20, as illustratedv in Fig. 2. .They effect of such adjustment 'of member 1K0 is lnot only to increase the pressure of spring 9 upon the lid but to load vand increase the resistance of valve I`21, to cause increased vapor or steam pres- ,sure within the'kettle due to the weight of rod 1.9 and its parts. By this means a variation of the pressure within the kettle may be made between thetwo extremes of the unloaded valve 21 and the valve when loaded by the, superimposed-weight of rod 19. yHaving now described our invention what ,we claim -isr- 1.
